i got pro comp ultra lite gauges boost and EGT. the boost likes to flicker a lot when boost numbers are higher and the egt works fine for a while then it starts to flicker all over and sometimes quit. I had the same problem with the last pro comp ultra lite gauges I had. Bought these bran new like 6 months ago really starting to tick me off auto meter suppost to be good stuff I had better luck with my glow shift. So im wondering am I the only one or is this just a crappy gauge selection. The EGT worked flawless for first month. Boost always been all over.

Try unplugging your alternator fuse that powers the fields. There may be some backfeeding of noise going on... My 2000 had similar gremlins, and I think it turned out to be part of the air dog solenoid/relay making noise.

Well I did some more research and lot of people said pyro's are real sensitive to a good ground so I gave it a good ground on the firewall and it sceems to be working just fine. So thought id put that out there in case someone else having same problem

I had a autometer pyro start intermitantly flickering too. Ended up being a loose ground screw for the gauge.
